VisiFault
Visual Fault Locator
Instruction Sheet
The VisiFault Visual Fault Locator (VFL) is a visible light source
that helps you trace optical fibers, check fiber continuity, and
find faults such as breaks, bad splices, and tight bends in fiber
optic cable.
Safety Information
W*Warning: Class 2 Laser
To avoid possible eye damage caused by hazardous
radiation
• Never look directly into the VFL’s output (item A in
Figure 1). Momentary exposure to the VFL’s output will
not damage your eyes; however, direct, long-term
exposure is potentially hazardous.
• Cover the VFL’s output with the dust cap when the VFL
is not in use.
• Do not open the case (except to open the battery cover
to change the batteries); no user-serviceable parts are
inside.
• Do not modify the VFL.
• Do not magnify or otherwise modify the laser output.
Use only approved connectors and adapters.
• Do not use controls, adjustments, or procedures not
documented or approved by Fluke Networks.

Using the Visual Fault Locator
To use the VFL, refer to Figure 1 and do the following:
1 Remove the VFL’s dust cap; then clean the VFL’s output
adapter and the connector on the fiber to be tested.
2 Plug the fiber optic connector into the VFL’s output (A).
The VFL’s universal fiber adapter accepts connectors with
2.5 mm ferrules (SC, ST, or FC). For 1.25 mm ferrules, use the
optional 1.25 mm universal adapter.
3 Press the key (B) to turn on the VFL.
4 To toggle between continuous and flashing modes, press
the FLASH key (C). The status LED (D) indicates the VFL’s
output status.
5 Turn off the VFL before disconnecting it from the fiber.
Replace the dust cap.
Tips: View the VFL’s light indirectly by holding a white card or
paper in front of the VFL output or the fiber connector
emitting the light.
The VFL’s light may not be visible through thick or dark-
colored cable sheaths or connector dust caps.
